"GPU hang" error on Thinkpad

n2o · Nov 27, 2019

This error on my Thinkpad T450s since about four weeks ago appears pretty regularily after a few minutes to an hour. I can't say what triggers it. The bios hardware check says the machine is cool. Fresh Solus install with one eopkg up and reboot.

Hi, maybe you can try this? (switch from sna to uxa acceleration)

https://bbs.archlinux.org/viewtopic.php?id=203123

I did not see your /var/log/Xorg.0.log so not so clear what settings gpu is using now

Please put long logs in https://pastebin.com/

You can try tweaking gpu here: /etc/X11/xorg.conf.d/20-intel.conf

With something like this in that file:

Section "Device"
 Identifier "Intel Graphics"
 Driver "intel"
 Option "DRI" "3"
 Option "TearFree" "true"
 Option "AccelMethod" "uxa"
EndSection

Maybe a good idea to look in that directory if there is already another file for intel gpu there

ls -l /etc/X11/xorg.conf.d/

RaMa · Nov 27, 2019

Another thing I find when searching around, it might have to do with iommu settings

https://centoros.wordpress.com/2015/07/22/iommu-dmar-fault/

I do not know your current kernel boot parameters, you could try adding or changing:

intel_iommu=on

or

intel_iommu=off

or

intel_iommu=pt

as a kernel boot parameter

It can be done here:

try ls -l /etc/kernel/cmdline.d/ to see what is already there

for example with a file 20-intel.conf with intel_iommu=something inside

after editing you have to run:

sudo clr-boot-manager update

to add that kernel boot parameter to the kernel in use, and then reboot

you can see the current kernel boot parameters with the command:

cat /proc/cmdline in a terminal

RaMa Hey thanks a lot for your ideas and the awesome explanations! I tried the uxa thing and now I haven't managed logging in anymore. The screen freezes as soon as I hit enter after password entry. Switching to a text console doesn't work either because my password contains an umlaut.

Just for curiosity: do you think it's likely that the machine has a hardware problem that the bios hardware check doesn't notice? I mean the machine ran fine for months until four weeks ago!

RaMa · Nov 27, 2019

OK, let's start with logging in, in text mode with other characters

You can use left-ALT + 0xxx codes, I just tried ä (left) ALT+0228 in a password and that works from a text tty

See here: http://www.irongeek.com/alt-numpad-ascii-key-combos-and-chart.html the right column!

Can you login, in that way?

You can test the umlaut in the username field, to see if it appears and then of course type the real username

RaMa · Nov 27, 2019

For more information about a probable cause look in the kernel log?

try: sudo journalctl -b -k --no-pager in a terminal

n2o · Nov 27, 2019

I tried the alt-0228 and a bunch of other methods - nothing works. But that's okay - it was a fresh test install anyway. I switched to a different machine for working, want to give this one to a friend and want him to use Solus. Now I quickly threw Ubuntu Mate on it to see what happens and so far it's fine without errors. I will let it sit there with something todo over night and tomorrow install Solus again to test your other suggestion!

RaMa · Nov 27, 2019

and the Xorg log:

cat /var/log/Xorg.0.log

RaMa · Nov 27, 2019

OK, good luck!

(left) alt-0228 is only for ä...

by the way, you have to input the numbers on the numeric keypad.... while holding left-alt ;-)

n2o · Nov 27, 2019

Uuugh the numeric keyboard, okay, that I did know about 20 years ago but had totally forgotten Thanks man and I will update you tomorrow!

RaMa · Nov 27, 2019

When releasing the alt key, the character appears! That is how it should work...

Yes, that was very long ago! :-)

n2o · Nov 28, 2019

Good morning! I spent another hour testing this in Solus. The iommu settings don't seem to be the culprit here either. I then downloaded standard Ubuntu gnome edition and installed that - it run's fine without problems.

So because I really have to go on with other stuff I now left Ubuntu on the machine for now and will give it to him like that. The issue seems to be a bug in something, probably upstream, in Solus. It runs fine on my machine and that's most important :-))

Thanks so much for your help, it is very much appreciated!

RaMa · Nov 28, 2019

Thank you, it was nice to meet you, Good luck!

RaMa · Nov 29, 2019

Today I installed Solus on an ASUS i7 Chromebox, there the video behaved strange, then I switched to LTS kernel, and it worked OK

So in case of video troubles that might help too...

n2o · Nov 29, 2019

RaMa I didn't even know, something like an LTS kernel existed. How does one switch to it? Using an XPS 13 i5 quad core now here and it works fine except for the mouse pointer stutter problem!

RaMa · Nov 30, 2019

You can install that via:

sudo eopkg it linux-lts

Or via software center...

Also set boot manager time-out to 3 or so, so you can choose that lts kernel at boot time in boot menu

sudo clr-boot-manager set-timeout 3

and then after reboot to automatic boot that chosen kernel

sudo clr-boot-manager update

bolofar · Nov 30, 2019

I can confirm the problem is caused by the kernel. The newest 5.3 also leads to frequent system freezes on an ASUS UX305. The LTS kernel did, however, not work for me. The special keyboard keys (e.g. volume or brightness) didn't work. Installing 5.2.20 solved the problem.

sudo eopkg it https://mirrors.rit.edu/solus/packages/shannon/l/linux-current/linux-current-headers-5.2.20-130-1-x86_64.eopkg

Don't forget to switch to this kernel with clr-boot-manager or by hitting space during boot (for UEFI boot).

You'd be then faced with the "problem" that the system wants to upgrade the kernel, which you'd need to avoid. Manually unselect the kernel in the GUI when upgrading or upgrade using

sudo eopkg up -x linux-current

n2o · Dec 1, 2019

Thank you, bolofar and RaMa for your instructions! I must admit that I have never even messed with the kernel of my system in any way because I know basically nothing about the technical work behind all that. I rather always rely/relied on a system just working.

Time is quite of the essence for me at the moment so I think I'll try to sit through this and hope to see those issues fixed within the next few weeks. As stated abive I now switched to a Dell XPS machine which seems to do mostly fine.

One last question: how "deep" is the integration between the OS (Solus in this case) and the kernel? Is it normal to kind of rip out one kernel and just pop in another to see where this is going? It seems like it is from what I read but as I said I never really worked under the hood a lot.

Thanks so much again!

RaMa · Dec 1, 2019

Hi

n2o how "deep" is the integration between the OS (Solus in this case) and the kernel?

Kernel is the core, where all is built around you could say, maybe you can see it as the foundation of a building, but then the changing appears not so easy as it is in a Linux based OS, so maybe easier to see it as the motor of a car... ;-)

Then the latest kernel (current) is a Tesla Elon Musk creation, and the LTS kernel is a Mercedes engine made in Germany proved by decades of experience...

And the changing of the kernel from the repository is not such a big issue, it is just a package like the other packages... already pre-made and tested to fit in, only if you remove all kernel packages you cannot drive around anymore :-)

n2o · Dec 1, 2019

RaMa Thanks! I'm curious where this road will lead.
